In addition to the areas described below, an evacuation meeting place will be designated before operation begins, based on the field activity planned. Work-zone boundaries will be delineated in the field, as necessary, using safety cones, barricades, and flagging tape. 8.1 Exclusion Area An Exclusion Area will be established to control access to the work areas and will extend from a distance of at least ten feet from the area where potentially-impacted media is being sampled or tested, and at least 25 feet in areas where drill rigs or heavy equipment is in use in the event significant concentration of hazardous material are encountered. The size and shape of the Exclusion Area will be determined based on wind direction, effective Site security, surrounding operations, and surrounding public areas. Level D protection will be required at a minimum for all personnel within the Exclusion Area. • 8.2 Contamination Reduction Area A Contamination Reduction Area will be placed in an area adjacent to and upwind from the Exclusion Area. In this area,personnel and equipment will be decontaminated, as appropriate, after work has been completed. Potentially contaminated trash will be accumulated in this area. 8.3 Support Area The Support Area covers all areas outside the Exclusion and Contamination Reduction Areas.
